WIRE-ROPE SHAQKLE FOP.- AUTOMOBILE VJHEELS.

Oliginal application filed March 3, 1917, Serial No. 152,218. Divided and this application filed March 2, 1920. Serial No. 363,088.

To all whom it may concern Be it known that I, Eaton E. CHAPMAN, a citizen of the United States. residing at Los Angeles, Los Angeles County, and State of California, have invented a new and useful Improvement Comprising ire-Rope Shackles for Automobile \Vheels, of which the following is a specification.

My invention relates to shackles whicl are adapted to be secured about the wheel of an automobile torthe purpose of preventing theft or unauthorized use thereof. Such shackles are ordinarily secured about one of the front wheels being locked there around so that the shackl is difficult to remove and so that they will producean unmistakable sound and make a plain trail in case the automobile is operated with the shackle in place thereon.

An object of the invention is to provide a shackle for this purpose which will make an unmistakable sound, preventing the automobile from running at a high speed, and which will also leave a distinctive mark on the surface of the street in case theauto mobile is driven with the shackle in the place on the wheel thereof; For this purpose I provide a bumping member which is secured on the tread of a tire and provided with a sharp projection so placed as to dig into the street it the automobile is moved with the shackle in place.

A further object of my invention is to provide a shackle which may be adjusted to suit different diameters of tire in different sizes of telly.

Referring to the drawing whirh is tor illustrative purposes only, Fig. l. is a View of cross section through a tire with the shackle in place thereon.

Fig. 2 is a side elevation of same.

In the form of the invention illustrated in the drawing a bumping member 11 is provided with the pointed projection 12 which is of proper shape to leave a distinctive mark on the surface of the street in case the automobile is operated with the shackle in place thereon.

Secured in the member 11 at either end thereof are wire rope'members 13 and 14-], these members being preferably formed of hardened steel so they cannot be readily cut or broken. Each of these wire rope members passes through a hole in one of the heads 15 and 16, being secured therein by a set screw 17 which is inserted from the inner side so it cannot be tampered with ere cept when the shackle is on the wheel. The heads 15 and 16 are locked toge-tl'ier by a bolt 18 controlled by a lock 19.

'ln'practice the members 125 and la: are made sufficiently long for the largest diameter of tire with which they are likely to be used. When the shackle is sold, however. the dealer adjusts the members 13 and 1 1 to the size of tire for which they are to be used, that adjustment being accomplisehd by loosening the set screw 17 and moving the members 13 and l t into the proper position in the heads 15 and 16. It will be noted that the telly 20 of the wheel fits up inside the heads 15 and 16 thus preventing them from being rotated with the block 11 in place on the tire 21.

This application is a division or my application Serial No. 152,213, filed March 3, 1917, and entitled Improvement in vehi ole shackles.

I claim as my invention:

1. A shackle for an automobile wheel comprising a bumping block; two flexible wire arms, one secured to one side of said block and the other secured to the other side of said block; two heads each secured to the other end of one of said wire arms; and

means for locking said heads together.

2.21 shackle for an automobile wheel comprising a bumping block; two flexible arms formed of wire rope, one secured to one side of: said block and the other se cured to the other side of said block; two heads each secured to the other end of one of said wire arms; and means for locking said heads together,

3. A shackle for an automobile Wheel comprising a bumping block; a projection forming a portion of said bumping bloc-k. said projection being so shaped that it will leave a plain mark in the surface of the street it the wheel of the automobile is 1'0- tated with the shackle in place thereon; two flexible wire arms, one secured to one side of said block and the other secured to the other side of said block; two heads each secured to the other end of one of said wire arms; and means for locking said heads together.

1. A shackle for an automobile wheel comprising a bumping block; a projection forming a portion of said' bumping block, said projection being so shaped that it will leave a plainmark in the surface oi the street if the wheel of the automobile is r0- tated with the shackle in place thereon; two flexible arms formed of. wire rope, one secured to one side oi said block and the other secured to the other side of said block; two heads each secured to the other end of one of said wire arms; and means forlocking said' heads together.

5; A shackle for an automobile wheel comprising a bumping block fitting over a the secured on said wheel and having a projection extending outwardly beyond the tread of said tire, said projection being of such size and shape as to permit the wheel to be freely rotated with the signal in placethereon, th-usraising the wheel from the ground and imparting a marked bumping motion thereto; two flexible wire arms, one secured to one side of said block and the other secured to the other side ofi said=bloekg two heads each secured to the" other end of one of said wire arms; and means for looking said heads together.

6. A shackle for an automobile wheel comprising a bumping block fitting over a tire secured on said wheel and having a pro- 1ect1on extending outwardly beyond the tread of said tire, said-projection being of such size and shape as to permit the wheel to be freelyrotated with the signal in place thereon, thusraising the wheel from the ground and inmartinga marked humping motion thereto; two flexible arms formed of wire r0 )0 one secured. to one side of said.
